1. INTRODUCTION
This manual contains all the necessary information on operation of the Energic Plus LF battery
chargers.The installation, comissioning and some of the maintenance operations should only be
carried out by professional technicians. A separate manual is available especially for the technician to
complete the installation and commissioning.
If you require this information and the maintenance steps, please contact your dealer.
Also included in this manual are a number of safety instructions to create a safe working environment.
The Energic Plus LF battery chargers have been designed to charge Pb batteries. These units can
convert the AC input voltage to a DC voltage at the correct level, in order to charge the battery cells.
Please read the manual thoroughly and observe the safety procedures before putting the unit into
operation. Contact your dealer for any further questions or concerns you may have.
Please read the manual thoroughly and observe the safety procedures before putting the unit into

carefully and regularly and have access to it at all times.
Keep this manual in a safe place for future reference.
Contact your dealer for any further questions or concerns you may have.
We hope you will enjoy working with your LF battery charger.
If you wish to use these LF battery charger in extreme conditions such as extreme heat,
extreme cold, extreme drought, etc. Please contact your dealer to discuss whether this
product is suitable for the activities you wish to undertake with the LF battery charger.
In the annexes of this template (see chapter 12) you can find a section on first aid. Please read
this chapter thoroughly before you start.
When recharging the batteries, make sure that they are in a well-ventilated area, as the
charging process generates hydrogen gas that is explosive in certain concentrations in air (the
flammability or explosive limits are 4.1% to 72% hydrogen in air). The spark-retarding vents
help slow the rate of release of hydrogen, but the escaping hydrogen may form an explosive
atmosphere around the battery if ventilation is poor.

To protect against shock, have a qualified electrician verify that the equipment is adequately
grounded and learn what terminals and parts are electrically hot.
Do not try to charge other batteries than Pb batteries.
Check the battery type and the recommended type of charger.
The LF battery chargers may be unsafe if adequate maintenance is neglected. Therefore,
adequate maintenance facilities, trained personnel and procedures should be provided.
Maintenance and inspection shall conform to the following practices:
1. A scheduled planned maintenance, lubrication and inspection system should be followed
(see maintenance instructions chapter 8).
2. Only qualified and authorised personnel shall be permitted to maintain, repair, adjust and
inspect the LF battery chargers.
3. Modifications and additions which affect capacity and safe operation shall not be
performed by the customer or user without the manufacturer’s prior written approval.

6. COMMISSIONING
This charger is designed for charging lead acid automotive batteries only. The charger converts the
AC input into DC, at the correct value to charge the battery.
The charger is only suitable for conventional charging applications.
The standard model of the LF chargers follows the Wa charging curve as described by the DIN 41774
norm.
The charger’s operation is controlled by a microprocessor. A typical charging cycle consists of 3 parts:
• INITIAL or BULK CHARGING
The battery is in a discharged state. The voltage of the battery cells is below the“gas”point
(i.e. approximately 2.40 V/cell at a temperature of 30 °C).
In this condition, the battery can absorb a large amount of energy. The charger operates close to its
maximum power, keeping the battery voltage under control.
• REDUCING or ABSORBERING THE CHARGING
The battery voltage exceeds the“gas”point. The electrolyte produces gas and the charging current
must be reduced to prevent the battery from overheating.The charger adjusts its output current
and finishes charging when it detects a full state of charge (= 100%).
• EQUALISATION
Once charging is complete, the charger automatically stops and allows the battery to cool. If the
battery remains connected to the charger for long enough (e.g. over the weekend), the charger will
emit additional, controlled, low current pulses. The purpose of this process, called“equalization”, is to
bring all the battery cells to exactly the same state of charge.
The battery chargers are equipped with two setting blocks, for selection of the nominal AC input
voltage and better optimization of the charging curve.
NOMINAL VOLTAGE 3-phase and 1-phase
This setting is present on chargers designed to operate with different nominal AC input voltages,
e.g. 3 x 230/400VAC or 1 x 208/240/480 VAC.
Some chargers use a screw-type terminal block for this setting, while others use a standard bar-type
(delta-wye) terminal block.
CHARGING CURVE OPTIMISATION
This setting is present on all LF chargers. Its purpose is to compensate for fluctuations in the AC input
voltage at the installation site.
It is recommended to check the actual value of the available AC input voltage at the installation site,
and adjust the charger output current accordingly.
A screw terminal block is used for this adjustment on all chargers. In the case of single-phase models,
one wire must be routed. On 3-phase models, three wires must be connected.
• Safe practices must be learned through study and training before using this equipment.
• Only qualified personnel should install or service this battery charger.
Before disconnecting the battery, check that it is not being charged. If it is charging, turn off
the charger using the main switch or the stop push button, to avoid sparks between
connectors.
If the RGB LED flashes, the charger is active. Do not disconnect the battery!
Only when the RGB LED shows a SOLID colour (also white) you can disconnect the battery.
